Issue
Cloud Firestore Database and Flutter.
My Implementation
AsyncSnapshot<QuerySnapshot<Map<String, dynamic>>> snapshot
After snapshot has data
if (snapshot.hasData) {
final List<dynamic> _products = snapshot.data!docs[0].data() as List<dynamic>
}
Value of the expression snapshot.data.docs[0].data()
using debugging I found it not null.
It is of the type _InternalLinkedHashMap
Solution
If the snapshot.data.docs[0].data()
shows up as a _InternalLinkedHashMap
it is a Map
and not a List
, so you can’t cast it to a list.
It sounds like you want:
snapshot.data.docs[0].data() as Map<String, dynamic>
If you get another error on that case, I recommend searching for the error message – as most of the common conversions have been covered before.
